Application led .uly 10,1915. Serial No. 39,083.

To all whom t may concern Be it known that I, PETER L. FERGUSON, a citizen of the United States, and a resident of Ogden, in the county of Weber and-State of Utah, have invented an Improvement in Trowels, of which the following is a specilication.

This invention relates to plastering tools, and more particularly to a trowel of novel construction whereby a suitable design of plaster cornices or moldings may be readily and uniformly made on the walls and ceiling of a room.

The primary object of the invention is the provision of a tool which is simple in construction, light, durable, and eflicient in carrying out the purpose for which it is designed.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying drawing, in which- Figure l is a sectional View on the line 1 1 of Fig. 3, showing the application of the invention. Fig. 2 is a side elevation, and Fig. 3 is a top plan view.

Referring more particularly to the accompanying drawing, in which like reference characters indicate similar parts, the numeral l indicates generally the body portion of the trowel, the same being preferably made of sheet metal, thus giving it the desired strength and rigidity. The body portion is composed of the top 2, preferably of rectangularr formation and the sides 3. Two adjacent sides of the body portion are indented to provide communicating guide grooves 4 for the purpose which will hereinafter appear. The other sides of the body portion are provided with suitable handles 5 used for the purpose of operating the trowel. Extending across the body portion from the corner at which the grooves 4 meet to the diagonally opposite corner is a vertically arranged reinforcing partition 6.

A plate 7 is carried by the top 2 of the body portion extending diagonally across the same and preferably in a line. with the partition 6. The plate 7 is arranged at right angles to the to-p 2 as clearly illustrated in Fig. 3 of the drawing, so that the device may be eifectually operated from either direction in making the cornice or molding. It is also obvious that said plate need not be arranged in a line with the partition 6 but may also be extended at an angle t0 the line of said partition. The plate 7 is preferably of substantially triangular form and is provided on its' outer edge with any suitable design or configuration for forming the co-rnices or moldings and arranged in aline substantially parallel with said configuration, said plate is provided with a reinforcing rib 8.

In practice, when it is desired to use the trowel, a plurality of guide strips 9 are secured in a horizontal position to the walls of the room and strips 10 are similarly secured to the ceiling. The guide grooves 4 are adapted to engage the strips 9 while plate 7 is provided at its top with a reduced portion 1l adapted to receive the guide strips 10. In the formation of the cornices the handles 5, are grasped and the trowel moved along the wall and ceiling in the direction indicated by the arrow in Fig. 3. l/Vhen the corner of the room is reached, the guide groove 4 which is not in engagement with one of the strips 9 will then engage the strip extending at right langles to the one secured to the wall upon which the cornice has just been formed. The trowel is then moved along the latter strip to form the cornices on the wall to which said strip is secured and similarly notch 11 in the plate 7 will engage each succeeding guide strip 10. It will thus be seen that in forming the cornices the trowel is guided through its entire movement whereby uniformity and smoothness in the formation of thel cornices or molding will be obtained.

I claim:

l. In combination, guide strips adapted to be attached to the walls and ceiling of a room, a molding device comprising a body portion, two o-f the adjacent sides of which are indented to provide angular guide grooves for receiving certain of said guide strips, and a plate carried by said body portion and having a. configuration on one edge thereof, and another edge thereof being provided with a reduced portion to form a guide groove adapted to receive other of said guide strips to support said molding device in operative position.

'2. A device of the character described comprising a body portion including a top and sides, two of the adjacent sides being indented to provide angular guide grooves, a plate carried by said top and arranged at an oblique angle thereto, one edge of said plate being provided with a suitable configuration, and a reinforcing rib for said plate extending substantially parallel with the edge thereof containing the configuration.

3. A device of the character described comprising a body portion including a top and sides, tWo Vof the adjacent sides being indented to provide angular guide grooves,

a plate carried by said top and arranged at an oblique angle thereto, one edge of said plate being provided With a suitable configuration, a reinforcing rib for Said plate extending substantially parallel With the edge thereof containing the configuration, and a diagonally extending reinforcing partition for said sides.
